Description
Technical field
It the utility model is related to a kind of grommet, and in particular to one kind reduces car noise grommet.
Background technology
Composite bush is the spherical bronze powder of intermediate sintering using steel plate as matrix, surface rolling polytetrafluoroethylene (PTFE) and lead it is mixed
Compound, is the composite bush rolled.It has that friction coefficient is small, and wear-resisting, corrosion resistance is good and the characteristics of oil-free lubrication.Make
The advantages that being reduced cost, the mechanical volume of diminution with this product, be avoided stinging axis phenomenon and reducing mechanicalness noise, it is widely used in
The accessory of automobile.But also there is the problem of easy to wear in the normalization used with automobile, composite bush；It is and existing
Bushing is usually complicated, it is easier to the problem of deepening abrasion.
The content of the invention
The utility model aim is to provide a kind of reduction car noise grommet for overcome the deficiencies in the prior art.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：One kind reduces car noise grommet, it is wrapped
Include cylindricality matrix, be opened at the cylindricality matrix center and its with the through hole with same axial line, be set in the cylindricality
Shell body on matrix outer circumferential surface, be inserted in the interior tube body being in contact in the through hole and with the cylindricality matrix inner wall, open up
In in the cylindricality matrix and the multiple tracks arc-shaped slot that sets at equal intervals and being arranged on the multiple of the cylindricality matrix both ends of the surface
Protrusion, arc-shaped slot described in per pass is through the cylindricality matrix and parallel with the axial line of the cylindricality matrix, described in each road
Spacing between arc-shaped slot and the cylindricality matrix axial line is equal.
Optimally, the spacing for defining the arc-shaped slot and the cylindricality matrix side face is d1, the arc-shaped slot and institute
The spacing for stating cylindricality matrix inner wall is d2, and d1/ d2 are 0.5 ~ 2.
Since above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：The utility model
Car noise grommet is reduced, by being arranged shell body on cylindricality matrix periphery, interior tube body is set at interior bone, and in column
The arc-shaped slot at interval is set in shape matrix, is so conducive to simplify the structure of grommet, improves the integral strength of grommet, mitigates mill
Damage, and advantageously reduce car noise.
Brief description of the drawings
Fig. 1 is the structure diagram that the utility model reduces car noise grommet；
Fig. 2 is the side view of Fig. 1.
Embodiment
The utility model preferred embodiment is described in detail below in conjunction with attached drawing：
Reduction car noise grommet as depicted in figs. 1 and 2, mainly include shell body 1, cylindricality matrix 2, interior tube body 4,
Arc-shaped slot 5 and protrusion 6 etc..
Wherein, through hole 3 is offered at the center of cylindricality matrix 2, through hole 3 has through cylindricality matrix 2 and with cylindricality matrix 2
There is same axial line, the edge of such through hole 3 forms the inner wall of cylindricality matrix 2.Shell body 1 is set in the outer of cylindricality matrix 2
On side face, interior tube body 4 is then plugged in through hole 3 and is in contact with 2 inner wall of cylindricality matrix, so utilizes shell body 1 and interior tube body 4
Cylindricality matrix 2 can effectively be supported.Arc-shaped slot 5 is then opened in cylindricality matrix 2 and sets at equal intervals, per pass arc
Shape slot 5 is through cylindricality matrix 2 and parallel with the axial line of cylindricality matrix 2 so that each road arc-shaped slot 5 and cylindricality matrix 2
Spacing between axial line is equal, i.e. projection of the arc-shaped slot 5 on 2 end face of cylindricality matrix is on same circle（The circle and column
The end face of shape matrix 2 is concentric）；Protrusion 6 has multiple, they are separately positioned in the both ends of the surface of cylindricality matrix 2；So be conducive to letter
Change the structure of grommet, mitigate abrasion, and advantageously reduce car noise.
In the present embodiment, the spacing for defining arc-shaped slot 5 and 2 side face of cylindricality matrix is d1, arc-shaped slot 5 and cylindricality base
The spacing of 2 inner wall of body is d2, then d1/ d2（That is the ratio of d1/ and d2）For 0.5 ~ 2.
Above-described embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement according to this, the scope of protection of the utility model can not be limited with this,
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover the scope of protection of the utility model it
It is interior.
